Hopper — AI Agents for Mainframe Operations - Hypercubic
Hypercubic
Agentic TN3270 emulator that lets AI agents operate z/OS: navigate ISPF, write column-strict JCL, debug jobs, and query VSAM.
Key features
- Agentic TN3270 Emulation: Provides a real TN3270 terminal interface that AI agents can interact with to perform terminal-based workflows and operations inside z/OS.
- Model Context Protocol Integration: Connects AI agents to mainframe systems via Model Context Protocol, enabling contextualized, stateful interactions and natural-language commands.
- ISPF Navigation and Interaction: Lets agents navigate ISPF menus, edit dataset members, and perform common ISPF tasks programmatically to automate operator workflows.
- Column-Strict JCL Generation: Generates, validates, and edits column-strict JCL compliant with mainframe formatting rules, reducing errors and manual rework.
- Job Debugging and JES Integration: Diagnoses failed jobs by examining JES output, suggests fixes or corrective JCL edits, and supports resubmission workflows.
- VSAM and Dataset Querying: Enables agents to query, inspect, and modify VSAM files and other datasets directly from the terminal context for data investigation and remediation.
- Autonomous Workflows and Natural-Language Ops: Orchestrates multi-step autonomous tasks initiated via natural language, combining terminal actions, queries, and code edits.
- Knowledge Capture and Documentation: Records operational procedures and extracts institutional knowledge from mainframe artifacts (COBOL, JCL) for documentation and modernization.

Best for
- Automated Job Recovery: Detect failed batch jobs, analyze JES logs, generate corrected JCL, and resubmit jobs with minimal human intervention to reduce downtime.
- JCL Authoring and Validation: Produce column-strict JCL for new or migrated batch processes, validate formatting and dependencies, and enforce site-specific JCL standards.
- Dataset Investigation and Remediation: Locate datasets via ISPF, query VSAM contents, identify data issues, and apply scripted fixes or migration steps.
- COBOL Documentation and Knowledge Capture: Extract program structure and business logic from COBOL sources, generate human-readable documentation, and preserve institutional knowledge.
- Operator Onboarding and Assistance: Provide interactive, agent-guided terminal sessions that teach new operators how to navigate ISPF and perform common operational tasks.
- Legacy Modernization Workflows: Automate discovery, refactoring, and migration tasks for legacy workloads by combining terminal interactions with scripted modernization procedures.
- Automating routine mainframe operations (job submission, debugging)
- Generating and validating column‑strict JCL
- Exploring and querying VSAM/datasets via agents
- Accelerating COBOL/mainframe modernization tasks
- Providing hands‑on evaluation environments for mainframe dev teams
- Automated mainframe operations and incident remediation
MCP Bridge — Connect any API to any AI agent
AppFactor
Auto-generate MCP tool definitions from REST, GraphQL, SOAP, or gRPC APIs to connect any API to any AI agent, self-hosted and production-ready.
Key features
- Schema Import: Supports OpenAPI (JSON/YAML), GraphQL introspection, WSDL (SOAP) and gRPC (server reflection or .proto files) via URL, paste, or file upload to onboard APIs without code changes.
- Auto-generated MCP Tools: Converts each API operation into a fully typed MCP tool with input/output schemas, parameter mappings, descriptive documentation, and behavioural annotations for accurate agent discovery and invocation.
- Runtime Validation & Mapping: Validates inputs against generated schemas, maps parameters and authentication details, and forwards requests to backend services while preventing malformed calls.
- Response Post-processing: Normalizes and trims API responses to reduce token consumption and produce agent-friendly outputs, improving cost-efficiency and relevance when used by LLMs.
- Authentication & Governance: Centralizes handling of API authentication, rate limiting, and access controls so agents call services securely without shipping credentials or custom glue code.
- High-performance Rust Core: Built in Rust for memory safety and high throughput to support production-scale deployments with minimal runtime dependencies.
- Deployability & Marketplaces: Self-hosted in minutes with availability via AWS Marketplace and Microsoft Azure Marketplace, enabling enterprise deployment patterns and marketplace procurement.
